IMPROVEMENT IN NUT-LOCKS.

Specification forming part of Letters Patent No. Is 1,4 [9, dated August22, 1876; application filed June 5, 1876.

To all whom ct may concern:

"Be it known that I, DANIEL DESHON, of

had to the accompanying drawings, and to the.

letters of reference marked thereon, which form a part of thisspecification, and in which .Figure l is a plan view of my improvednutloek as applied for use in connection with railroad-rails 5 Fig. 2, atransverse section thereof, and Fig. 3 a side view of the same.

Corresponding parts in the several figures are designated 'by likeletters.

This invention relates to a certain improvement in nut-locks; andit'consists ofa spring or plate, with tapering apertures or openings toreceive correspondingly beveled or chamfered. nuts upon bolts passingthrough the said spring or plate, 8250., substantially as hereinaftermore fully set forth. i

In the annexed drawing, A refers toa plate or spring, with its inwardlycurved or bowed central portion a and its correspondinglycurved ends a apressing against the fish-bar 1), connecting the sections ofrailroad-rails c 0 together. to illustrate one of the uses to which mynut-lock may be applied. The isolated portions of the spring or plateAare provided with apertures oropenings a a for the passage of thenutted ends of the bolts cl d, connecting the fish plates or bars I) bto the sections of railroad-rails c 0, they, in turn, connecting thesaid sections together. The apertures or openings a a of the spring orplate A taper inwardly, or widen toward the nuts 6 e to receive thesame, correspondingly beveled or chamfered to fit therein, as clearlyseen in Fig. 2.

By this construction, when the nuts are screwed up sufficiently to bringthe pressure of the spring or plate A against them, the chamfered orbeveled surface thereof will enter the tapering apertures and pressagainst their beveled or chamfered sides, and be thus firmly lockedthereto, and prevented from. turning and leaving their bolts whensubject- I claim, and desire to secure by Letters Patent, is

The bowed plate or spring A, having tapering apertures or openings a ato receive, and in combination with, the bolts (1 d, beveled orchamfered nuts 0 c, and fish bars or plates 1) b, substantially as andfor the purpose set forth. g

In testimony that I claim the foregoing as my own 1 hereunto at'fix mysignature in presence of two witnesses.
